Default 91 Civic Si, 1.6L head gasket/head bolts/valve stem seals

Want to purchase the head gasket, head bolts and valve stem seals for my 1991 Honda Civic Si, 1.6L, Hatchback, (D16A6).

I have the following part#s so far and want to make sure they are the correct parts before I purchase them:

Gasket, Cylinder Head (Ishino Gasket) - Honda (12251-PM5-S02)
Bolt A, Cylinder Head Cover - Honda (90014-PM3-000)
Seal A, Valve Stem (Nok) - Honda (12210-PZ1-004)
Seal B, Valve Stem (Nok) - Honda (12211-PZ1-004)

Question on the valve stem seals.
I see that there are two different part numbers for the valve stem seals, Seal A and Seal B. How many do I need to buy of each?
Never done this job before so its a learning experience for me.


Any advice is greatly appreciated

for your valve stem seals you need 8 of each
8 for intake side and 8 for exhaust side

if you want head bolts, they are 90005-PM3-004 bolt/washer (10 required) - the 90014-PM3-000 bolts are for the valve cover (2 required) - they bolt down the camshaft cap near the distributor and have threaded stud on top for the valve cover

the numbers you have for valve stem seals are correct - seal A is for the intake valves and seal B is for the exhaust valves

head gasket part no. is correct

Friend has a 1994 Honda Civic Lx (1.5L) and also has a blown head gasket but he's going to try to fix his issue using "Bar's Leak HG-1 HEAD SEAL Blown Head Gasket Repair".

What are the Pros and Cons?

I found a remanufactured head for sale by J and C Enterprises (e bay). Cost is $249, One year warranty.

What are things to watch out for when going this route and buying a head off of e bay.
HONDA CIVIC CRX 1.5 1.6 16V SOHC NON-VTEC CYLINDER HEAD CASTING PM3 PM9 88-95 | eBay


Anyone know of a good shop in the Los Angeles area where I can take the head in for a rebuild?

Purchased a used head for 150$.

Going to start removing bolts and other parts so that I can get access to the cylinder head

Question?
Do I turn the crank shaft clockwise or counter clockwise to reach Top Dead Center (TDC) at the number 1 cylinder?
